Food for thought: Using food delivery services to provide rapid cardiac arrest response and potentially save lives

A simulation presented in the Canadian Journal of Cardiology explores leveraging an existing food delivery network to provide more rapid defibrillation to out-of-hospital patients

2025-08-28
(Press-News.org) Inspired by an urgent need to improve timely defibrillation for out-of-hospital cardiac arrests (OHCA) in dense urban settings, a team of investigators developed a simulation that explored the potential of leveraging an existing food delivery network in Taipei City, Taiwan, to help address this challenge. Their findings in the Canadian Journal of Cardiology, published by Elsevier, suggest that deploying food delivery riders to deliver defibrillation may reduce automated external defibrillator (AED) response times by approximately three minutes—about 50% faster than a traditional emergency medical system (EMS)—and might be particularly beneficial during peak hours.

Lead investigator Kuan-Chen Chin, MPH, Department of Emergency Medicine, Taipei Hospital, Ministry of Health and Welfare, New Taipei City, and Department of Emergency Medicine, National Taiwan University Hospital, Taipei City, Taiwan, explains, “Each minute of delay in defibrillation reduces the survival rate by 7–10%. Our approach leverages an existing, widespread urban workforce to address a well-known weak link in the chain of survival. We found that it offers a cost-effective and scalable strategy for improving OHCA outcomes in high-density cities, where EMS cannot always provide immediate defibrillation.”

Densely populated Taipei has a high concentration of food delivery (FD) scooter riders. To examine the feasibility of utilizing these FD riders as first responders for AED delivery in OHCA incidents investigators conducted a city-scale simulation using real-world OHCA data from the Registry of the Taipei City Fire Department between 2017 and 2019, public defibrillator locations, and food delivery patterns and hotspots using the Uber Eats platform.

The simulation assumed that every open restaurant in a hotspot had one FD rider waiting and ready to respond to OHCAs within a two-kilometer radius. FD riders’ response rates were varied, and simulated defibrillator arrival times were compared to documented fire department delivery times of six to seven minutes. Differences in defibrillator arrival times during peak and off-peak hours were also assessed.

With a 10% FD rider response rate, the defibrillator arrival time decreased by 2.99 minutes, representing approximately 44% of the original EMS response time. In the simulation, over 60% of OHCAs were successfully attended. Achieving 80% coverage during peak hours required 13.4% of FD riders to respond.

According to co-corresponding investigator Albert Y. Chen, PhD, Department of Civil Engineering, National Taiwan University, Taipei City, Taiwan, “Integrating FD riders into the EMS system could reduce defibrillator arrival times, decreasing patient waiting time for defibrillation. This approach is particularly effective during peak hours, when a higher proportion of OHCAs can be addressed.”

“We were encouraged to see that even low response rates might yield meaningful time savings, and that the model appeared effective during off-peak hours despite reduced availability,” adds co-corresponding investigator Jen-Tang Sun, MD, MS, Department of Emergency Medicine, Far Eastern Memorial Hospital, New Taipei City, Taiwan.

College drinking linked to poor academics, mental health for those around the drinker: Study

2025-08-28
By Paul Candon PISCATAWAY, NJ – It’s well known that alcohol misuse can harm not only drinkers themselves but also those around them. Now, a new report in the Journal of Studies on Alcohol and Drugs shows that, among college students, harms such as lower grades, mental distress and even suicidal thoughts are linked to being exposed to a drinker’s poor behavior. “We often think of alcohol’s harms as physical or social, but this was the first study to assess academic harms from others’ drinking, like having to drop a class or take on extra work,” says lead researcher Pamela ...

Nearly 80% of whale sharks in this marine tourism hotspot have human-caused scars

2025-08-28
Whale sharks, the largest living fish species, are classified as endangered on the IUCN Red List of Threatened Species. Over the past 75 years, populations have declined by more than 50% worldwide, and by up to 63% in the Indo-Pacific region. Because whale sharks take up to 30 years to become sexually mature, populations can only recover slowly from threats like hunting for fins, meat, and oil, habitat loss, and entanglement in fishing nets. Now, an international group of researchers has shown that in the Bird’s Head Seascape off Indonesian West Papua, 62% of whale sharks have scars and injuries from preventable ...

Spider uses trapped fireflies as glowing bait to attract more prey

2025-08-28
Ecologists have observed a species of nocturnal spider attracting prey to its web using the bioluminescent beacons of already trapped fireflies. This rare example of a predator exploiting its prey’s mating signal for its own gain is documented in the British Ecological Society’s Journal of Animal Ecology. Researchers at Tunghai University, Taiwan have observed sheet web spiders Psechrus clavis capturing fireflies in their webs and leaving them there while they emitted bioluminescent light for up to an hour. The researchers even observed the spiders going to check on the captured fireflies from time to time. Intrigued ...

How AI can build bridges between nations, if diplomats use it wisely

2025-08-28
Dr Donald Kilburg, who was a member of the US Department of State, says the technology is already shaping work for the likes of embassy officials whose jobs are to protect their country’s interests abroad. But the US army veteran and retired professor warns that algorithms cannot ‘read the room’, and can’t replicate the ‘empathy, intuition and deep cultural understanding’ of human diplomats. He says: “AI can streamline diplomacy, but only humans bring the empathy and intuition that make negotiations ...

2025-08-28
A recent survey commissioned by The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) focused on Americans’ awareness of the signs and symptoms of prostate cancer. The survey results show most people (80%) don’t know early-stage prostate cancer often presents with no physical symptoms, typically only diagnosed with a blood test. Prostate cancer affects more than 300,000 adults in the United States ...

Researchers engineer ureter tissue from stem cells, paving way for transplantable kidneys

2025-08-28
Scientists at Kumamoto University have made a major breakthrough in regenerative medicine by successfully creating functional ureter tissue—organoids resembling the urinary tract—from pluripotent stem cells. The achievement brings researchers one step closer to developing transplantable kidneys capable of producing and expelling urine. The ureter, a critical tube that carries urine from the kidneys to the bladder, has long been missing from lab-grown kidney models. Without it, kidney ...

Strong, evidence-based leadership at CDC essential in wake of director’s exit, says SHEA

2025-08-28
SHEA is deeply disappointed by the sudden departure of the CDC Director so soon after her confirmation, at a time when the agency most needs stability and authority to carry out its vital mission of protecting the health and safety of all Americans. The United States stands at a critical crossroads, where strong, trusted public health leadership is essential to restoring confidence through evidence-based practices and guidance. In an era marked by increasing assaults on science and public health, CDC must be empowered to rise above politics and remain focused on their core purpose: safeguarding ...

Birdwatching tourism is booming. Some countries are benefiting, while others are left behind

2025-08-28
Deep in a forest in the Andes, high atop a tall tree, there’s a quick, colorful flash of plumage in vivid shades of yellow, green, and blue. A high-pitched musical chirp rings out. Through a carefully trained pair of binoculars, a beautiful little bird comes into view. It’s a multicolored tanager, a species that lives only in the mountains of Colombia. Seeing it in person for the first time feels like the thrill of discovery. Watching it search for fruit across the treetops brings a sense of peace and connection to nature.  Experiences like these are what motivate birdwatchers to travel the globe, in hopes ...

High protein or Trp diet increases the risk of cancer-associated venous thromboembolism

2025-08-27
Contact: Gina DiGravio, 617-358-7838, ginad@bu.edu (Boston)—Next to cancer recurrence or progression, cardiovascular diseases are the leading causes of death in cancer survivors. The Surveillance, Epidemiology, and End Results database revealed that among the more than three million who initially survived cancer between 1973 and 2012, 38% eventually succumbed to the disease while 11.3% died from cardiovascular diseases.  Specifically, cancer survivors are at a four to seven-fold higher risk of venous thromboembolism ...

Risk of a second cancer after early breast cancer is low

2025-08-27
For women diagnosed with early breast cancer, the long-term risk of developing a second primary cancer is low (around 2-3% greater than women in the general population), finds a study published by The BMJ today. The researchers say this information can help reassure many breast cancer survivors who believe their risk of a second primary cancer is much higher than these results suggest. Breast cancer survivors are at increased risk of developing second primary cancers, but risk estimates from previous studies are inconsistent. ...
